Cortex
Cortex is a horizontally scalable, highly available, multi-tenant, long term storage for Prometheus.
Features
- Horizontally scalable: Cortex can run across multiple machines in a cluster, exceeding the throughput and storage of a single machine.
- Highly available: When run in a cluster, Cortex can replicate data between machines.
- Multi-tenant: Cortex can isolate data and queries from multiple different independent Prometheus sources in a single cluster.
- Long term storage: Cortex supports S3, GCS, Swift and Microsoft Azure for long term storage of metric data.
